Abstract

We report on experimental proves of light-induced changes in the transmission spectrum of human venous blood under the action of low- intensity radiation from He-Ne laser. The transmission spectra of diluted and nondiluted heparinized human blood have been analyzed before, after and in the course of irradiation. The reproducible variations of the blood transmission spectrum in the range 730-780 nm have been observed. These changes have been shown to correlate with oxygen saturation. The decreased oxygen saturation in venous blood is stabilized at the level of about 70-80% from the initial one after 5-8 procedures of laser irradiation.
